WebAug 16, 2024 · The measured biasing current of the peaking current source used in Rec1 is shown in Fig. 4.18a, which matches well with simulation results. The peak current is designed to be around 4.1 μA when the supply voltage is 2.3 V, and the minimum bias current is 3.2 μA when V DC = 3.8 V. WebThe peak current is the maximum amount of current which output is capable of sourcing for brief periods of time. When a power supply or an electrical device is first turned on, high initial current flows into the load, starting at zero and rising until it reaches a peak value, known as the peak current.
